lMPl 20\ EMENT IN WlND -POWER MACHINES.

Specification forming part of Letters Patent N 0, 175,545, dated March 28, 1876; application filed August 20, 1875.

To all whom it may concern.-

Be it known that I, HORACE WOODRUFF, of Sandwich, in the county of De Kalb, and in the State of-Illinois, have invented certain new and useful Improvements inWind-Power Machine and do hereby declare that the folits construction and operation, referring to the annexed drawing, which represents a perspective view of my invention.

A represents a frame of suitable construction, which restsand turns freely upon the turn-table E, to which is rigidly attached the vane or rudder G. This turntable turns freely upon the pipe F, and is supported by the collar F,'which is firmly secured to the The main shaft B-is provided with a crank, actuating thepitman G, which is attached to the slotted vertical arm L, projectin g from the oscillating shaft K, which is also provided with a horizontal curved lever, D,

for the purpose of giving the pump-rod I a vertical reciprocating motion. The curve in the lever D is to accommodate its working over the main shaft, and the slot in the arm L admits of the adjustment of the pitman 0 so asto give a greater or less motion to the rod I. It therefore follows that the rotating ot' the main shaft by the wind -wheel gives the pitman a horizontal reciprocating motion, and, by being connected with the oscillating shaft, having its two levers at right angles, gives the pump-rod the vertical motion desired. The face of the wind-wheel is held at right angles with the direction of the wind by a weighted lever, B, holding it at right angles with the direction of the rudder, the rudder pointing to the wind under all circumstances.

' To govern the mill so asnot to injure it by too rapid motion, the adjustable governors'H are provided, which, being attached to the frame, and at right angles with the rudder when the mill is in motion, counteracts or eounterbalances the effect of .the weighted lever B, andin heavy gales nearly overcoming it, turning the faceof the wind-wheel obliquely to the wind,.so that it will preserve so as to present their smallest surface to the wind, and brought as near the vertical line of the turning-point of the frame as possible. Intermediate positions give intermediate speeds.

Having thus fully described myinvention,

what I claim as new, and .desire to secure by Letters Patent, is I The combination of the crank-shaft B, pitman 0, slotted arm L, oscillating shaft K, and curved lever D, all constructed substantially as and for the purposes set forth.

In testimony that I claim the foregoing I have hereunto set my hand' this 15th day of June, 1875.
